(KMOV) -- A sixth-grader was suspended Wednesday morning after bringing a plastic pellet gun to a south St. Louis elementary school.

According to Patrick Wallace with the St. Louis Public School District, a male 6th grader was suspended after he brought a plastic pellet gun to Long Elementary.

Authorities say some sort of behavior signaled administrators to talk to the student shortly before 7 a.m. The school principal and the school resource officer called the student into an administration office where they discovered the pellet gun in a binder.

The plastic gun did not set off the school's metal detectors and it was not loaded. Police say the weapon did have a bright orange tip.

Juvenile detectives were called to the school but do not plan to pursue criminal charges. The pellet gun is not considered an illegal firearm.

School officials believed the student did not threaten or intend to threaten anyone with the weapon as it was inside the student's binder. The student was issued an automatic 10-day suspension per the district's policy.

A letter was sent home with students and robo-calls calls were placed to parents informing them of this incident and the forthcoming letter.
